A system for controlling cycling operations of backup battery units configured to supply backup electrical power to electronic components in a datacenter, the system comprising: electronic components having a power demand; backup battery units configured to supply backup electrical power to the electronic components; power supply units configured to supply electrical power to the electronic components, each of the power supply units being configured to switch between receiving electrical power from a primary power supply and a respective one of the backup battery units; and a controller comprising a processor and memory containing executable instructions that, when executed by the processor, cause the controller to: receive a request to cause a selected backup battery unit of the backup battery units to undergo a cycling operation; receive information indicative of a total power capacity of a remaining set of the backup battery units not including the selected backup battery unit; determine the total power capacity of the remaining set of the backup battery units based on the information; compare the total power capacity of the remaining set of the backup battery units to a threshold, the threshold being based on the power demand of the electronic components over a predetermined period of time; and prevent the selected backup battery unit from initiating the cycling operation in response to determining that the total power capacity is below the threshold.

Plain English Translation

A system manages backup battery units in a datacenter, ensuring continuous power to electronic components. It includes electronic components with a power demand, multiple backup battery units, and power supply units that can switch between primary power or a backup battery. A controller, with a processor and memory, receives a request for a specific battery to perform a maintenance "cycling operation." It then determines the total power capacity of all *other* remaining batteries. This remaining capacity is compared against a threshold, which is based on the electronic components' power demand over a set period. If the remaining battery capacity is below this threshold, the system prevents the selected battery from starting its cycling operation to maintain sufficient backup power.

Claim 2

Original Legal Text

2. The system of claim 1 , wherein the executable instructions are further configured to cause the controller to: query a subset of the power supply units associated with the remaining set of the backup battery units to determine whether any one of the remaining set of the backup battery units is offline; and prevent the selected backup battery unit from undergoing the cycling operation in response to a determination that any one of the remaining set of the backup battery units is offline.

This remaining capacity is then compared against a threshold, which is based on the electronic components' power demand over a set period. If the remaining battery capacity is below this threshold, the system prevents the selected battery from starting its cycling operation. Conversely, if the controller determines that the total power capacity of the remaining set of backup battery units *exceeds* the threshold, it will allow the selected backup battery unit to undergo its cycling operation.

Claim 5

Original Legal Text

5. The system of claim 1 , wherein: the backup battery units comprise six backup battery units; and when each of the six battery backup units is in a new condition and fully charged, a total power capacity of any five of the six battery backup units meets or exceeds the power demand.

If it is determined that the total power capacity of the remaining batteries is *not* sufficient to satisfy the power demand, the system then prevents the selected backup battery unit from undergoing its cycling operation. This prevention is performed via the power supply unit that is operatively coupled with the selected backup battery unit. Furthermore, the method involves providing a dedicated controller, which is configured to communicate with each of the power supply units. This controller is then responsible for querying the remaining set of backup battery units to determine the status of each individual battery unit, facilitating capacity assessment.

Claim 14

Original Legal Text

14. The method of claim 7 , wherein: the request to cause the selected backup battery unit to undergo the cycling operation is received by a selected power supply unit associated with the selected backup battery unit; and the selected power supply unit queries other power supply units associated with the remaining set of the backup battery units to determine a status of each backup battery unit of the remaining set of the backup battery units.

Plain English Translation

A method manages backup battery units to supply backup power to an electronic device, such as datacenter components. The method begins by receiving a request for a specific backup battery unit, chosen from a group of multiple units, to perform a maintenance "cycling operation." This request is specifically received by a selected power supply unit that is associated with the selected backup battery unit. Next, it determines whether the total power capacity of all *other* remaining backup battery units (not including the selected one) is sufficient to satisfy the power demand of the electronic device. To do this, the selected power supply unit queries other power supply units that are associated with the remaining set of backup battery units to determine the status of each of those remaining battery units. If it is determined that the total power capacity of the remaining batteries is *not* sufficient to satisfy the power demand, the system then prevents the selected backup battery unit from undergoing its cycling operation. This prevention is performed via the power supply unit operatively coupled with the selected backup battery unit, ensuring backup power.

Claim 15

Original Legal Text

15. The method of claim 14 , further comprising: receiving a second request to cause a second selected backup battery unit of the remainder remaining set of the backup battery units to undergo a second cycling operation; and preventing the second backup battery unit from undergoing the second cycling operation in response to the second request being received after the request to cause the selected backup battery unit to undergo the cycling operation.

Plain English Translation

A method manages backup battery units to supply backup power to an electronic device, such as datacenter components. It receives a request for a specific backup battery unit to perform a cycling operation, with this request initially received by the power supply unit associated with that selected battery. This PSU then queries other PSUs connected to the *remaining* backup battery units to determine their status and total power capacity. The method determines if the total capacity of these remaining batteries is sufficient for the electronic device's power demand. If not, the selected battery is prevented from cycling via its associated power supply unit. Additionally, if a second request is received for a *different* backup battery unit (from the remaining set) to undergo a second cycling operation, and this second request arrives *after* the first request, the second backup battery unit is prevented from cycling. This ensures that only one battery undergoes cycling at a time to maintain system redundancy and power availability.

Claim 16

Original Legal Text

16. A system, comprising: a controller comprising a processor and memory containing executable instructions that, when executed by the processor, cause the controller to: receive a request to cause a selected backup battery unit to undergo a cycling operation, wherein backup battery units configured to supply electrical power to a shared power demand comprise the selected backup battery unit; determine whether a remaining set of the backup battery units can supply sufficient power to meet or exceed the shared power demand, wherein the remaining set of the backup battery units does not include the selected backup battery unit; and prevent the selected backup battery unit from undergoing the cycling operation in response to determining that the remaining set of the backup battery units cannot supply sufficient power to satisfy the shared power demand.

Plain English Translation

A system manages backup battery units, comprising a controller with a processor and memory containing executable instructions. When these instructions are executed, the controller receives a request for a specific backup battery unit to undergo a maintenance "cycling operation." These backup battery units collectively supply electrical power to a shared power demand, such as datacenter components. The controller then determines whether the remaining set of backup battery units (excluding the selected one) can supply enough power to meet or exceed this shared power demand. If the controller determines that the remaining backup battery units *cannot* supply sufficient power to satisfy the shared power demand, it prevents the selected backup battery unit from undergoing its cycling operation. This ensures that critical systems maintain continuous backup power even when a battery needs maintenance.

Claim 17

Original Legal Text

17. The system of claim 16 , wherein: each of the backup battery units is operably connected with a respective power supply unit for supplying power to and receiving power from the backup battery unit; the controller comprises a power management controller; and the executable instructions are further configured to cause the power management controller to communicate with each of the power supply units via a common bus.

Additionally, each backup battery unit in this system is operably connected with a respective power supply unit for power transfer. To determine the status of the remaining battery units, the controller is specifically configured to query a designated "master device" that is selected from among these power supply units.

Claim 19

Original Legal Text

19. The system of claim 16 , wherein: each of the backup battery units is operably connected with a respective power supply unit for supplying power to and receiving power from the backup battery unit; and the controller is configured to query a controlling power supply unit temporarily selected from among the power supply units to determine a status of each backup battery unit of the remaining set of the battery backup units, the controlling power supply unit corresponding to the selected backup battery unit.

Furthermore, each backup battery unit is operably connected with a respective power supply unit. The controller is configured to query a "controlling power supply unit," which is temporarily selected from among the power supply units and specifically corresponds to the *selected* backup battery unit itself. This controlling power supply unit then determines the status of each backup battery unit in the remaining set.

Claim 20

Original Legal Text

20. The system of claim 16 , wherein a total power capacity of the backup battery units exceeds the shared power demand by at least an amount corresponding to a first capacity of one of the backup battery units, such that a subset of the backup battery units can provide power equal to or exceeding the shared power demand when one or more of the backup battery units are taken offline.
